An autonomous and decentralized protocol for delay sensitive overlay multicast tree

Abstract

In this paper, we present a protocol for dynamically maintaining a degree-bounded delay sensitive spanning tree in a decentralized way on overlay networks. The protocol aims at repairing the spanning tree autonomously even if multiple nodes' leave operations or failures (disappearances) occur simultaneously or continuously in a specified period. It also aims at maintaining the diameter (maximum delay) of the tree as small as possible. The simulation results using ns-2 have shown that the protocol could keep reasonable diameters compared with the existing centralized static algorithm even if many nodes' participations and disappearances occur frequently.

An Efficient Overlay Multicast Protocol for Heterogeneous Users

“…The detailed comparison of MODE with the existing work is described in Ref. (4). Inheriting the advantage, MODE-m in this paper can adaptively determine the positions of mobile nodes to prevent these incapable nodes from affecting the diameters.…”

“…The basic idea is inspired from the protocol MODE 4) , which is one of our prior works. Mobile nodes we discuss here are nodes with low-bandwidth and less capability of computing, which are connected via wireless links to wired networks.…”

“…In such an environment, overlay multicast should be constructed carefully and dynamically to prevent those hosts from staying at critical positions that affect the diameter and stability of the overlay multicast. The protocols MODE in our previous work 4) and OMNI 5) have presented distributed solutions for the requirements (i) and (ii). However, as far as we know, none of the existing work, including MODE and OMNI, has not dealt with the third issue, which is a very important issue to realize seamless communication between non-mobile and mobile nodes in group communication.…”

Stability Oriented Overlay Multicast for Multimedia Streaming in Multiple Source Context

“…This is also critical when using ALM in real world applications. Multiple path approaches where the redundant paths are used in case of original path failure ( [5], [6]), or restore schemes where the overlay topology is re-established using a previously or immediately calculated restore mission ( [7], [8], [9]) are often used to realize this. The third one corresponds to the ALM schemes like [10], [11], [12], which are targeted to provide some other QoS features like bandwidth.…”

Design and Implementation of Overlay Multicast Protocol for Multimedia Streaming

“…They are classified into the following three categories based on their policies to generate overlay topologies, (i) mesh-first approaches like [1,2], (ii) tree-first approaches like [3,4,5,6,7] and (iii) other approaches like [8]. In Ref.…”
